When he was offered a toast during the Nobel function being a strict abstains completely from alcoholic beverages he responded: Sir, you have seen the Raman effect on alcohol; please do not try to see the alcohol effect on Raman. Raman was a great lover of music. He used to say: I should live long, […]Continue reading…

Advantages of Raman Spectroscopy many organic and inorganic materials are suitable for Raman analysis. These can be solids, liquids, polymers or vapors. no sample preparation needed. not interfered by water. non-destructive. highly specific like a chemical fingerprint of a material. Raman spectra are acquired quickly within seconds. samples can be analyzed through glass or a […]Continue reading…

Number and symmetry of vibrations With any molecule, the energy can be divided into translational energy, vibrational energy and rotational energy. Translational energy can be described in terms of three vectors 90° to each other and so has three degrees of freedom. Rotational energy for most molecules can also be described in terms of three […]Continue reading…

Quantum theory When light interacts with matter, the photons which make up the light may be absorbed or scattered, or may not interact with the material and may pass straight through it (Smith and Dent, 2005). When monochromatic light interacts with molecules, most of the photons are scattered without any change in energy. This process […]Continue reading…

A large variety of spectroscopic techniques are available for the analysis of materials and chemicals. Among these is Raman spectroscopy. Raman spectroscopy is based on the Raman effect which has been discovered by experiments of Sir C. V. Raman in 1928. In 1930, Sir Raman received the Nobel price for this discovery. This relies on […]Continue reading…

Ok, now I want to share a minor tip about how to write cm-1 very fast and very simple (in Microsoft Word). First of all discussion about this shortcut, I want to be clear: ctrl+c -> ctrl+v. This is commonly used shortcut, but in some cases (for whatever reason) we can not use. What to […]Continue reading…
